In the related art, the zoom effect is generated by adjusting the positions of the lens, the object and the focus. When shooting, when the imaging surface moves along the axis of the lens, the visual angle and the focal length change, so that a scene at a far distance can be clear. That is, by changing the focal length of the lens to change the angle of view of the photographing, the photographed object is "zoomed in" or "zoomed out", achieving optical zooming. Terminal equipment such as mobile phones produced by many manufacturers often adopt long focus and fixed focus to realize a zooming function, the zooming capability is up to about 10 times, and the quality of a shot picture can be influenced by larger zooming times, so that the use experience of a user is influenced.
In the related art, terminal equipment such as a mobile phone is limited by the structure of the terminal equipment, and the aperture of the terminal equipment such as the mobile phone is a fixed aperture, so that the problems of complex structure and high manufacturing cost exist, the aperture size cannot be changed, the light inlet quantity cannot be adjusted, the requirements of various shooting environments cannot be met, and the user experience is poor. For example, due to the transitional exposure under strong light, the shot picture is too bright and white; for another example, due to underexposure in weak light, the photographed picture has problems of darkness, high noise and serious detail loss.
